NUT-LUCK- SPEGIFICATION forming part of Letters Patent No. 759,039,dated May 3, 1904..

Serial No. 177,155. (No modeld To a 'lllhOlH/ it mJ/r/y concern:

Be it known that I, \VILLIAM M. SMITH, a citizen of the United States ofAmerica, rcsiding at Tlurtlecreek, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements inNut-Locks, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to certain new and useful improvements innut-locks; and the primary object of the invention is to provide novel,inexpensive, and effective means for the secure locking of a nut on itsbolt.

A further object of my invention is to provide a device for this purposethat may be advantageously used in almost any connection where it may bedesired to securely hold the nut in the locked position, the devicebeing applicable as well for the locking of a nut that is adjacent towood as one adjacent to a metal piece through which the bolt is passed.

Briefly described, my invention comprises a nut-holding device made froma single piece of sheet metal, in'eferably stamped from the sheet inorder to reduce the cost of manufacture to a minimum. This nut-holdingdevice comprises two integral members, one of which is apertured toreceive the bolt and the other of which is adapted to engage with andhold the nut. The apertured member is provided with a tongue formed bymaking two slits in the member extending from the wall of the apertureinto the member toward the nut-engaging member, and this tongue isadapted to be bent out, so that the major portion thereof will lie on aplane beyond the face of the member and which is adapted to engagein anotch or recess provided therefor in the member through which the boltis passed.

The invention will be hereinafter more fully described and thenparticularly claimed, and in describing the invention in detailreference will be had to the accompanying drawings, forming a part ofthis application, and wherei n like numerals of reference will beemployed for designating like parts throughoutthe different views of thedrawings, in which Figure 1 is a horizontal sectional view showing theapplication of one form of my improved nut-lock to railroad use. Fig. 2is an end view of the nut-lock in position. Fig. 3 is a plan view of oneform of blank before being bent into shape for locking the nut. Fig. 4is a perspective view of the same form of blank bent into shape forlocking the nut. Fig. 5 is aplan view of a modified form ofconstruction. Fig. 6 is a like view of another modi'lication. Fig. 7 isa side or edge view of the form of lock shown in Fig. 5 in position onthe nut, the latter being shown in dotted lines. Fig. 8 is a like viewof the form of lock shown in Fig. 6, the nut being shown in dottedlines.

In Figs. 1 and 2 of the drawings I illustrate the application of myimproved nut-lock in connection with forming a railjoint, 1 indieatingthe web of the rail, and 2 3 the fishplates. The belt 4 with which myimproved nut-lock is employed and also the nut 5 may be of the usualform of construction, requiring no alteration whatever to effect thelock of the nut on the bolt. When used in connection with a rail-joint,1: form a notch or recess 6 in the face of the fish-plate 3, said notchor recess registering with the aperture in said plate through which thebolt iis passed. This notch or recess is adapted to receive a tonguemember carried by the locking device, as will be more fully explainedhereinafter.

The locking device embodies an integral bolt-receiving member and anut-engaging member. As shown in Figs. 1 to 4;, inclusive, the lockingdevice is cut from a single piece of material, preferably stampedtherefrom, the bolt-receiving member 7 being connected to thenut-engaging member 8 by means of a short shank 9. In this form ofconstruction the member 8 is provided with an aperture corresponding incontour to the nut which it to receive, the said member 8 surroundingthe nut when in the locked position, though I may, as will hereinaftermore fully appear, engage the one member with the side of the nutinstead of providing said member with an opening to receive the nuttherein. The memher 7 is provided, substantially in alinement with theshank 9, with a pair of slits l0, and the material between these slitsis bent or struck out beyond the plane of the remainder of the blank toform a tongue 11, extending in alinement with the member 7 and isadapted to engage in a notch or recess provided therefor in the outerface of the object through which the bolt is passed, as in the notch orrecess 6. preferably slightly tapered, as best seen in Fig. 3, easilyaccomplished by making the slits 1O somewhat Vshaped-*that is, cuttingaway more of the material at the outer than at the inner end of theslits, said outer or free end extending in a plane transverse to thelongitudinal plane of the bolt. In using the form of device shown indetail in Figs. 3 and 4 the blank, as seen in Fig. 3, has the bolt 4passed through the receiving-opening in member 7 and the tongue 11 isengaged in the recess 6. After the nut 5 has been screwed home themember 8 is bent over so as to surround the nut, as seen in Figs. 1 and2, securely preventing the nut from turning by reason of the engagementof the longitudinal edges of tongue 11 with the longitudinal wallsformed by recess 6.

As shown in Figs. 5 and 7 the bolt-receiving member 7 is provided with atongue 1]. and is made integral with a nut-engaging member ofsubstantially T-shape, embracing the shank 9 and right-angular lugs orcars 10, While in Figs. 6 and 8 the bolt-receiving member 7 has a tongue11 and an extending shank or lug 10 In the construction shown in Figs. 5and 7 the shank 9 is bent up along the side of the nut 5 and the lugs orcars 10 bent over thereagainst, as seen in Fig. 7, while with theconstruction shown in Figs. 6 and 8 the extension or shank 10 is bent upalongside the nut at right angles to the body of the washer-blank, thetongue engaging in a recess in the object through which the bolt ispassed to prevent turning of the nut.

The bolt receiving member acts as the washer between the nut and theobject through (Shown in Fig. 1.) This tongue is which the bolt ispassed, and the nut engaging the outer face of this washer securelyholds the tongue in engagement in the recess in said object, the nutbeing prevented from loosening by the engagement therewith of the othermember of the blank. WVith either of the forms of construction shown anddescribed it will be observed that I am enabled to stamp the same out ofsheet metal, making the same extremely inexpensive, and thereforeadapted for use in various different connections. When the form shown inFigs. 3 and 4: is employed, it is preferable to make the shank 9 widestat the end adjacent to the receiving member 7 in order not to weaken thedevice by the slitting thereof to form the tongue.

In the practice of the invention it will be observed that various slightchanges may be made in the details of construction without departingfrom the spirit of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A nut-lock formed from a single piece of material, and comprising anapertured boltreceiving member, a nut-receiving member, and a taperingshank joining the members, the shank at its widest end joining with theboltreceiving member, the said two members adapted to be bent to lie ata right angle to the shank, and a tongue formed by providing thebolt-receiving member with a pair of slits in the perforation thereof inthe side adjacent the shank and nut-receiving member, said tongueadapted to be bent outward to lie in a plane beyond the bolt-receivingmember, substantially as described.

In testimony whereof I affix my signature in the presence of twowitnesses.
